Just how do you know that she didn't try that approch 1st?
We haven't seen anything other than a quick overview. It was a mean spirited statement, if untrue. It may very well have been said in the hopes of hurting this woman more than had already been done. For all we know, she may have lodged the complaint that got her band from the mall in the 1st place.
I have always been a believer that you should be able to confront you accuser. If someone doesn't dare let anyone know who they are, they must not want people to form an opinion of their character.
This attitude that she is stupid, if she wants to find out who said this about her, is like the people that say a rape victim must have been at fault because she enticed man. How fair is that?
